Thermostatic valve for thermal engine refrigeration circuit, has connecting piece that kinematically links piston and sealing valve when pressure difference on either side of sealing valve is lower than predefined value

摘要

The valve (30) has a thermostatic component with a piston (3) that moves with respect to a body containing wax. A connecting piece kinematically links the piston and a sealing valve when the pressure difference on either side of the sealing valve is lower than a predefined value. The connecting piece facilitates the displacement of the sealing valve with respect to the piston along the direction of displacement of the piston. The sealing valve moves with respect to a casing for regulating the passage of a fluid between a fluid inlet orifice and a fluid outlet orifice of the casing.
